Abstract

Insights

For mycosis fungoides, combination therapies show limited superiority over monotherapy. Certain combinations like PUVA with interferon-alpha or retinoids, and methotrexate with interferon-alpha or bexarotene, may benefit specific patient groups.

Area of Science:

  • Dermatology
  • Oncology
  • Clinical Pharmacology

Background:

  • Mycosis fungoides, a common cutaneous T-cell lymphoma, lacks curative treatments.
  • Combination therapies are established for increasing efficacy, but clinical trial data are scarce.

Purpose of the Study:

  • To review evidence on combination therapies for mycosis fungoides.
  • Focus on psoralen with UVA phototherapy (PUVA), interferon-alpha, and bexarotene combinations.

Main Methods:

  • Systematic literature review.
  • Databases searched: Embase, Cochrane, Medline, and Medline in Process.

Main Results:

  • PUVA combined with interferon-alpha or retinoids did not improve response rates.
  • Methotrexate may enhance interferon-alpha response; retinoids did not.
  • Bexarotene with methotrexate showed potential benefit, unlike with vorinostat or gemcitabine.

Conclusions:

  • No combination therapy definitively surpasses monotherapy for mycosis fungoides.
  • PUVA with interferon-alpha/retinoids and methotrexate with interferon-alpha/bexarotene may be beneficial in specific scenarios.
  • Bexarotene combinations with vorinostat/gemcitabine are not recommended due to side effects.

Cancer Therapies

Cancer therapies are various modes of treatment, such as surgery, radiation therapy, and chemotherapy that are administered to cancer patients.
However, cancer treatments can pose several challenges, as therapies used to kill cancer cells are generally also toxic to normal cells. Moreover, cancer cells mutate rapidly and can develop resistance to chemical agents or radiation therapy. Besides, all types of cancer cells may not respond to the same therapy. Some cancer cells respond to one...

Combination Therapies and Personalized Medicine

Combining two or more treatment methods increases the life span of cancer patients while reducing damage to vital organs or tissue from the overuse of a single treatment. Combination therapy also targets different cancer-inducing pathways, thus reducing the chances of developing resistance to treatment.
The combination of the drug acetazolamide and sulforaphane is a good example of combination therapy to treat cancer. The cells in the interior of a large tumor often die due to the hypoxic and...

Skin Diseases and Disorders

Skin is the first line of defense and encounters a variety of microbes. Some pathogenic strains are often the cause of a broad range of infections of the skin and other body systems. These conditions can affect people of all ages and may have different causes, including genetic factors, infections, autoimmune reactions, environmental factors, and lifestyle choices.
Gram-positive Staphylococcus spp. and Streptococcus spp. are responsible for many of the most common skin infections. However, many...
